   Here is another test case that prints out a bunch of `ThreadTraceApply` errors:
   
   ```
   import tvm
   from tvm.script import tir as T
   
   @T.prim_func
   def matmul(
       A: T.Buffer[(512, 512), "float32"],
       B: T.Buffer[(512, 512), "float32"],
       C: T.Buffer[(512, 512), "float32"],
       )->None:
       for i in range(512):
           for j in range(512):
               for k in range(512):
                   with T.block("update"):
                       C[i, j] = C[i, j] + A[i, k] * B[j, k]
   
   s=tvm.meta_schedule.tune_tir(matmul, "llvm --num-cores 1", tvm.meta_schedule.TuneConfig(100, 32), "tmp")
   ```
   
   I tested it with the commit before #12720 and still got a bunch of errors. Not sure if it is related to this.
